So my buddy and i took out his 13 for a spirited ride last nite and he wanted to try the launch control. We took a ride down to the beach where its very quite stopped the car put it in LC mode while the rpm was set to 3000 and the car fell on its face then took off producing 4.6 sec 0-60. We then moved the rpm limit up to 3500 and the car felt no different still fell on its face and produced a 4.7! So with this we moved to 4000 rpm and it fell on its face again! Now we aren't touching anything else but LC so im guessing maybe there is a better way for him to try. Also, his RPM setting goes down much lower then 3000 RPM, my 14 starts there! im guessing there was no reason to go below 3000 considering his car falls on its face up to 4000. Is there a better way to use this feature were it won't bog so bad? He is afraid to raise the limit any higher.
